646-648 Andover St, San Francisco, CA 94110

The 5-unit multi-family residential building at 646-648 Andover Street in Bernal Heights, constructed in 1908, has experienced several significant issues over the past two decades. The most recent concerning incident occurred in 2025 with a sewage backup discharge from the side sewer vent, though this was resolved through fieldwork. The property has documented multiple electrical system issues, notably in 2004-2005 when residents reported concerns about inaccessible electrical boxes, inadequate smoke detectors, heating problems, and an inaccessible power box that raised fire hazard concerns.

These electrical concerns were partially addressed through permits for switch installations in 2005-2007, though one panel permit from 2005 expired. The building has also faced various maintenance challenges, including complaints about peeling paint affecting the surrounding area in 2015, strong urine odors in the store section in 2000, and numerous instances of garbage and debris accumulation in recent years. The property has seen regular maintenance and operational issues with the storefront component, which has required various permits and has been subject to specific hours of operation restrictions (6am-10pm, with extended hours requiring conditional use approval).

Recent activity at the property includes several 311 calls in 2024-2025 regarding street and sidewalk conditions, including blocked sidewalks, fallen trees, and waste management issues. While many of these issues have been resolved through appropriate channels, the cumulative history suggests ongoing challenges with both building systems and property maintenance that have required active management over the years. The most significant cluster of building-specific complaints occurred between 2000 and 2015, primarily focusing on electrical systems, plumbing, and interior maintenance, though these issues appear to have stabilized in recent years.
